REFACTOR: rewrite CMakeLists.txt for better inlcude and reuse The rewrite uses more cmake build-in automatisms and build-in generates variables to allow better generic reuse. * cmake files are installed to ``` <install_prefix>/lib/cmake/nlohmann_json/ ``` for best support on most systems * include path is set to ``` include ``` for usage as ``` #include <nlohmann/json.hpp> ```

include_directories(${NLOHMANN_JSON_SOURCE_DIR})
Introduce structure to the test/ directory This introduces a clear separation between test data and test binaries. Test data is moved into test/data, and the test binaries move into test/src. A new CMake script specific to building the tests is introduced in /test to slightly clean up the toplevel one. As well as tidying things up, this makes the next step trivial...
